Thisinvention relates to liquid dispensing apparatus and more particularly to-apparatus fordispensing gasoline. I

One object is to provide a dispensing apparatus employing a meter as one of its elements, the meter delivering direct to a dispensing valve. Another object is to provide dial. pointers on the meter which can readily I be moved-back to zero after each lot of gasoline is dispensed. A further object is to provide quantity setting means which can be set for the number of gallons desired and which, when the set number of" gallons has been measured bythe meter, returns to zero position and automatically closesthe dispensing valve. A still further object is'to provide 1 means for setting the dispensing valve in either wholly or partly open-position to provide either a full or restricted flowv of gasoline.

5 Other objects and advantages of the invention will hereinafter appear in the following description and the novel features thereof will be particularly pointed out in the appended claims. I

Quantity measuring-means in'the form of a meter 1 (Fig. 1 is connected by pipe 2 (Fig. 10) to a dispensing valve 3. This dispensing valve 3 is normally held closed by spring 4 as shown, but when stem 5 is forced down by arm 6 carried by rock shaft 7, the valve is opened to of nipple 8. v

Extending up' from meter 1 is a shaft 9 (Figs. 2, 5) which through suitable gearing actuates shafts 10, 11, 12 (Figs. 4, 5) re-' 'spectivelycarrying indicating pointers 13,

14 and total index 15. I

The outer portion of shaft ,a10 carries pointer 13 for indicating gallons and fractions thereof, while pointer 14; on the outer portion of shaft 11 indicates up'to anumber of gallons.

The outer POIlZIOD. of shaft 10 comprises a shaft member 16 and two'hub members 17,

- 18/ Hub member 18 is freely rotatable on shaft member 1 6 and carries pointer 13 with a central hole 19 (Fig. 11) freely fitting over shaft member 16, the pointer being secured to through slots 2L (Fig. 11) Screw 22 secured end of shaft member 16 holds cover 23, spring 24 and thrust washer 25 in position.

permit flow of liquid out hub member 18 by screws 20. To permit the pointer to be adjusted so it will properlypomt to zero, screws 20 preferably pass The hub members 17, 18 have opposed friction cone clutch faces 26. Member 17 is slidable longitudinally thereon in any desired manner. Member 17 is normally forced into clutching engagement with member 18 by a\ relatively strong spring 27 engaged against pin 28. Spring-24 is relatively weak and is therefore compressed by strong spring 27 until the central area of pointer 31 thrusts against cover 23. The .function of spring24: will be hereinafter pointed out.

The outer portion of shaft 11 comprises a shaft member 29 and two hub members 30 31. Hub member ,31 is I freely rotatable on shaft member 29 and carrier pointer 14 fixed thereto by screws 32. Heads of screws 32 engage against thrust washer 33 held in place by screw.34 secured in end of shaft member 29. -Hub member is slidable longitudinally of shaft member 29 and may be secured non-rotatablythereon in any desired manner." Member 30 is normally forced into clutching engagement with member 31 by a spring 36 engaged against pin 37. Hub

members 17, 30 are 'rotatably supported'in frame 38 and have annular slots 39, 40 engaged by double end clutch release fork 41,

- which latter is engagedby arm 42 secured I on rock shaft 43 carrying operating lever or handle 44, for which purpose the release fork '41 is provided with an extension (shown in by additional mechanismas will now be described. A cam 46 is secured to hub Band has a V-shaped portion 47 pointed oppositely to the pointof pointer 13. Opposite V-shaped portion 47 is a V-shaped notch 48. Pivoted at 49 on frame 38 is a lever'50 weighted at 51 and having a hardened V-shaped block 52 adapted to fit notch 48. Disc 53 on the hub weighted lever the pointer at exactly zero.

18 guides lever in properposition on cam 46. When pointer 13 points downwardly V-point 47 of the cam 46 points upward, and V-point of block 52 ress'ing on one side or the other of .V-portion of 'cam 46 starts pointer swinging toward zero, the remaining movement of pointer toward zero being ac-.

complished by counterweight 45. When the pointer arrives near zero, V-block 52 of 51) enters'notch 48 and'stops Pointer 14 is normally swun to zero by counterweight 54 securedto hu 31. Lever 55 pivoted at 56 and having V-sliaped block 57 coacts with V-shaped notch 58 and V- shaped portion 59 on cam 60 to swing and stop pointer 14 at zeroin a way similar to the way pointer 13 is swung andstopped by corresponding'parts previously described.

Guide disc 61 aids in keeping lever 55 in properposition on cam 60.

Secured to hub member 18 is .anarm 62 having pin 63. Pivoted to frame38 at 64,-

65, are levers or arms 66, 67 'havingtheir outer ends normally held down by sprin s 68, 69 secured to depending portions 70, 1 of frame 38. The movement of levers 66, 67 is limited by abutments 7 2,7 3. The inner ends 78 being in such position that it strikes lever 79 by springing downward, lever 67 then springing upward to carry and retain hammer 78 out of contact with lever 79. 1

WVhen hub members 17, 18, 30, 31 are unclutched by pressing downward on lever 44, springs 27, 36 are considerably shortened by the backwardmovement of hubs 17, 30. When this happens, spring 24moves hub 18 back until pin 63 clears the path of can poitions 74, 7 5. Thus as pointers13 and 14 return to zero as previously described, cam portions 74, 75 do not interfere with the proper return of pointer- 13.

. Secured to frame portion 80 is a stud shaft 81. Pivoted at 7 9 is lever 79, which is normally pressed upward against abutment 82 by spring 83 mounted in barrel 84 secured on frame portion 80. Lever 79 has setting pawl- 85 adapted to normally engage one of a plu: rality of ratchet studs 86 on setting wheel 87 .journalled on stud shaft 81. Finger 108 is secured to frame portion 80 to act as a backing for pawl 85. A guide plate 88 abuts against shoulder 89 on stud shaft 81' and has fingers90, 91, one on each side of barrel 84 to prevent plate 88 from turning on shaft 81. Between plate 88and wheel 87 is a coil spring 92 having one end securedto shaft 81 at 93 and the other end bent. at 94 to engage any one of a plurality of pins 95.-

Setting wheel87 carries numerals on its edge 96 visibleat zero position 97 (Fig. 1) when in use. By turning wheel 87 clockwise. (Fig. 1.) by means of handle 98 the ratchet studs'86 depress pawl lever 79 as they ride overpawl 85, the lever 79 promptly rising to posltion again by action of spring 83.

If wheel 87 isturned to produce more than a certain tension on spring 92 the end 94 slips from oneto another of pins 95, thereby relievmg any excesstenslonon the spr ng.

ivoted at 99 is a set' and release pawl 100. w

Secured on shaft 7 is an operating lever 101 having a.tooth 102adapted to engageeither of notches 103, 104 on pawl'lOO. The other endof pawl 100 has acam face 105'and a locking face 106. When tooth 102 is engaged in notch 104 the valve will be fully open and will give a maximum rate of flow'of liquid. Wheel 87 has a pin 107 which, when the setting Wheel returns to zero as will be later described, first strikes camface 105'to release lever 101'tl1ereby closing the dispensing valve,-then engages I face 106 to stop the setting wheel to indicate zero.

Operation. By means of pressing down lever 44 both pointers will he made to stand at zero as previously described. By handle 98 setting Wheel 87 is turned clockwise until the desired number of gallons is indicated at 97-( Fig. 1). Lever 101 is then forced inward byhand until tooth 102 engages notch 103 for a restricted flow, or notch 104 for a full flow of liquid. This positioning ofthe lever 101 opens the dispensing valve against action of spring'4. Liquid then passes through me-' ter 1 by means of either power, hand, or air operation as described. As the liquid passes a through the meter 1, pipe 2 and dispensing valve 3, by means of shaft 9 and other mechanism previously described, the pointers 13,

14 move to indicate the amount of liquid pass-- were originally set to-dispense five gallons,

numeral five would show at 97 (Fig. 1) But when the first gallon was dispensed, the hand 13 had made one complete revolution back to zero, hand 14 indicated one gallon and the setting wheel had moved so that numeral 4 replaced numeral 5.. This action of hand 13 is repeated until hand 14 indicates five gallons and zero appears on the setting wheel at 97. As zero appears at 97, pin 107 depresses cam face 105 and raises notch 103 (or 104') out of engagement with the tooth 102, whereupon spring 4 closes the dispensing valve 3 and swingslever 101 to position shown in Fig. 7. It will be seen that valve opening lever 101 with tooth 102 will not engage with notch 103 or 104 until setting wheel 87 has been set to some numeral.
